The phrase every man (except Justin Beiber... just kidding, he isn't a man!) is required to say when the have sex. It must be said the instant you finish and you must tell 10,000 people by anymeans necesary. The creators of this tradition are The Lonely Island and Akon.

(Bill is having sex with Tracy and finishes and comes out of her and runs into traffic and says...) "I Just Had Sex!!!!!!!!!! And my dreams came true!!!!!!!!!"
